NGC 2288

NGC 2288 is a galaxy in the constellation Gemini about 253 million ly from Earth. It spans roughly 13,000 ly, about 13% of our Milky Way's width. The light reaching us tonight left it about 253 million years ago.

Because its light is 253 million ly from home, you are seeing NGC 2288 as it looked roughly 253 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
